SiC reduction crucible for sponge iron is sintered at high temperature with silicon carbide as aggregate and binder added. In addition to maintaining the good performance of SiC, a dense oxide protective film can be formed after the surface is oxidized to prevent further oxidation and has good resistance to Oxidative.

The SiC reduction crucible has good properties such as high temperature strength, high thermal conductivity, good thermal shock resistance and alkali corrosion resistance, and low thermal expansion rate, and has achieved excellent results in direct reduction iron kilns.

In the production of sponge iron by tunnel kiln process, the reduction crucible is placed on the kiln car, and the concentrate powder, coal powder and limestone powder are respectively loaded into the reduction crucible according to a certain proportion and charging method, and then pushed into the tunnel kiln. After the tank is preheated, heated, roasted and cooled, the concentrate powder is reduced to obtain sponge iron. This process has the advantages of mature and reliable process, low investment, quick effect, low cost, high and stable product taste, simple operation, stable equipment operation and low energy consumption, and is the most used process. The life of the silicon carbide reduction crucible used to hold iron powder in sintering is an important condition for the longevity of the kiln, and the life of the silicon carbide reduction crucible determines the efficiency and benefit of production.

SiC reduction crucible usage:

The SiC reduction crucible we produced are used in tunnel kilns for the production of sponge iron, and have been used by many large iron and steel enterprises with good results and are well received by customers! This product can also be used in the lower part of blast furnace body, furnace waist, furnace belly, tuyere combined bricks and tuyere sleeves, iron casting groove, iron furnace lining, coke oven furnace head, heating furnace slide rail, converter, electric furnace tapping hole, etc. , With high temperature wear resistance, slag resistance and alkali chemical corrosion, high thermal conductivity, oxidation resistance and thermal shock resistance, etc.

The direct reduced iron industry originally used clay crucibles, each crucible can only be used 3-5 times, and the pot diameter is small, the amount of product loaded is small, and the degree of automation is low. By using our company's production of SiC reduction crucibles, each crucible can be used at least more than 100 times, and the product is loaded with a large amount, which improves the output, ensures the quality, saves labor and a lot of money, and makes the majority of users feel the advantages of using SiC reduction crucibles.
