Metal silicon powder manufacturers have been established for many years and launched a large number of high -quality metal silicon powder to the market. With reliable quality and thoughtful service, they have won the recognition of many users. In order to return the majority of users for many years, and to allow more people to understand metal silicon powder, further promote the development of the industry, and briefly introduce metal silicon powder. Metal silicon powder can be used as a carbon hemestor or combustion agent according to different applications. Not every pure metal silicon powder can meet the standard. Let's introduce the quality indicators of stone metal silicon powder.1. Coke formed by small spheres, porous structures such as sponge -like, and coke formed by large small spheres. The structure is dense like a fiber or needle -shaped, and its quality is better than the sponge scorch. In the quality indicator, the real density roughly represents this performance, and the high density indicates good crystallism.2. Consider reflecting the powder coke and block granular coke in the coke.3. The content of sulfur and ash in oil coke. High -sulfur coke can cause qi bloating during graphitization, causing cracks in carbon products. High -gray points will hinder the crystallization of the structure and affect the use of carbon products.4. Coke products are resistant to cracking performance when they bear suddenly rising to high temperature or sharp cooling from high temperature cooling from high temperature.

In the metallurgical industry, the heating furnace is a device that heat metal objects such as iron plates and steel plates to rolled into forging temperature. The application of heating furnaces is widely used, such as petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, etc. There are different types of heating furnaces. Similar to other industrial kiln, the heating furnace consists of the shell steel plate and the inner lining refractory material. During the assembly of the refractory material for the furnace lining, the following standards must be met:1. The rust, welding residue and other dirt on the surface of the furnace should be removed before the furnace lining construction; the insulation nail (or insulation stent) should be welded should be anti -corrosion treatment in the furnace body.2. The welding material should be selected according to the material of the thermal insulation nail (or insulation stent); the insulation nail (or thermal insulation bracket) should be firmly welded and shall not be skewed.3. The bottom is a circular anchor part of the anchor. The other anchors should be welded along both sides on the wall board.4. The installation of folding ceramic fiber blankets shall meet the following requirements:1) Before installation, apply adhesives at the installation site. The adhesive should be evenly brushed and no leakage point.2) Folding ceramic fiber blankets should be flat. Uniform, the shape and size should meet the design pattern requirements, and the edges should be neat.3) When installing, all the supporting rooms should be installed, paved and covered, and then fixed with fixed nails after compacking.4) The indirect sewing of the blanket should be tight, and there must be no loosening, and no naked metal gaps and holes must be appeared.5) When installing a contraction compensation bar, the felt strip should be flat and beautiful with the folding ceramic fiber blanket.6) After the folding ceramic fiber blanket is qualified, the high temperature paint should be painted according to the design requirements.5. When installation of refractory fiber felt (blanket), the seams and layers of each layer should be applied to high temperature adhesives to make it closely fit. The seams should be sewed more than 100mm between the layers. During construction, the large compression amount of fiber felt (blanket) must not exceed 10%of the thickness.6. When the furnace wall is laid, the fire -resistant fiber felt (blanket) should be taken. If the installation should be placed flat, the pedal should be set up. The construction staff shall not step on the installed fiber felt (blanket). If the stove is installed on the top of the furnace, it should be fixed with a quick clip.7. During the construction of the furnace lining, the fiber felt (blanket) should be installed according to the size and position of the pipe rack. After the installation, all gaps are filled with refractory fiber felt (blanket), and then fixed with compressive tight slices or nuts fixation Essence8. After the furnace lining is installed, the heating nail head exposed in the furnace is applied to a high -temperature adhesive to paste the refractory fiber felt with 60mm × 60mm × 20mm to cover it.9. The spacing between the fiber -resistant fiber felt (blanket) edges and thermal insulation nails should be controlled at 78mm ~ 100mm.10. The quality of the furnace lining should meet the following requirements:1) The surface is flat, and there must be no defects such as gaps, cracks. Ritting angle, hair rising.2) Use 2000mm to check the flat furnace lining and round furnace lining. The vertical gap must not be greater than 10mm.3) Use a 1000mm long arc -shaped model to check the round furnace lining.4) The circularity permission in the cylindrical shell lining shall not be greater than 2%of its inner diameter, and must not be greater than 50mm.11. After the furnace lining is installed, it is strictly forbidden to impact hard objects and rainwater erosion.12. The steel wire mesh anchor should be pulled and welded before pouring.13. The construction of the brick structure furnace shall be implemented in accordance with the current national standards "Construction and Acceptance Specifications for Industrial Furnace Masonry Projects" GB50211.14. The construction of the pouring structure furnace shall be implemented in accordance with the current industry standards "Technical Conditions for the Lightweight Line Line Line Engineering of Petrochemical Pipe Furnace" SH/T3115 shall be implemented.

Silicon -manganese alloy balls are indispensable composite deoxidants during the steelmaking process. Compared with silicon manganese bricks, they are only different in shape. In the steelmaking alloy, the amount of silicon iron and silicon manganese can be reduced. The market price is relatively stable, the cost performance has outstanding advantages, and it has a wide range of applications in the field of steelmaking.Silicon -manganese alloy alloy is a alloy composed of manganese, silicon, iron and a small amount of carbon and other elements. Because manganese and silicon are the main alloy elements used in carbon steel, manganese is also one of the main deoxidants in the steelmaking process. Almost all steel types need to use manganese for deoxidation. Therefore, silicon manganese alloy balls are also a kind of steelmaking. The deoxidant commonly used in the process. When deoxidation is used, the melting point generated by the generated oxide is low and easy to float; in addition, manganese can also increase the deoxysentery effect of strong oxygen such as silicon and aluminum. The silicon manganese alloy ball has a large density and high purity. After use, there is no much pollution to steel water. The recovery rate is stable. The recovery rate reaches more than 95%. Improving the absorption of carbon in steel water, shortening the deoxidation time, improving the efficiency of steelmaking steelmaking, and reducing the cost of manpower and material resources. The higher income rate has high economic benefits compared to the separate carbon or manganese alloy. Generally speaking, the silicon manganese alloy ball is mainly used as the middle material of the dehydration agent and alloy agent of steel production, and it is also the main raw material for low -carbon manganese iron production. The raw materials for manganese silicon alloy include manganese ore, manganese -rich residue, silica, coke, white clouds (or limestone), fluorite. The production of manganese silicon alloys can use a mixed mine with one manganese or several kinds of manganese ore (including manganese scum). Because the content of iron and phosphorus in manganese silicon alloys is lower than that of high -carbon manganese iron, manganese ore with manganese silicon alloy is required to have higher manganese iron ratio and manganese phosphorus ratio. The higher the manganese ore containing manganese, the better the indicators.

1. Determine the demand. Before buying a silicon carbon alloy, users need to analyze which type of silicon carbon alloys need to be purchased. After clarifying the purchase object, it can not only save a lot of unnecessary trouble, but also be faster and accurate. Buy suitable, practical silicon carbon alloy.2. Determine whether the quality of silicon carbon alloy is qualified and whether it meets production needs. After selecting the manufacturer, the user should check the silicon carbon alloy. In this regard, the manufacturer can be tested from the manufacturer. If the test results meet the requirements, they can be purchased in large quantities. Instead.3. The qualifications of silicon carbon alloy manufacturers, when buying silicon carbon alloy, only pay attention to the quality of silicon carbon alloy itself, but also ignores the strength of the manufacturer. In fact, a good silicon carbon alloy factory is not only mature in production equipment, but also rich in production experience.
