The production process of chromium drainage sand?
The drainage agent is called drainage sand, which is divided into various series of products such as chromium, pheasant, and silicon. According to the different situations of each steel mill, it is used to use products that are suitable for production, which are mainly used in steel and refined color.
Chrome drainage sand is often in high temperature in the steel forage water outlet for a long time, so the fire resistance is high. Because the drainage sand is filled in the water inlet and directly received the steel. Therefore, the sintering temperature should not be too high; in order to prevent the role of huge steel water in the process of use and prevent the shed, the quantitative lubricant needs to be added, thereby reducing the friction between the drainage sand particles.
The automatic opening rate of chromium drainage sand is more than 95%. Generally silicon, magnesium drainter is suitable for short -process steelmaking technology; ordinary chromium drainters are suitable for the refining time of less than 45 seconds or non -refined steelmaking; Pour rate. Combined with the working principle of drainage sand in the LF/VD steel bun water mouth, it focuses on analyzing the physical properties of four types of chromium drainage sand, stalks] chromium drainage sand as the filling material for the steel forage water mouth, and improve the use of steel bags in actual production status The automatic opening rate of steel bags can be greatly improved, thereby improving production efficiency. Chrome drainage agent selected imported high -pure chromium sand as the main raw material, with fine grinding spherical silicon sand, with a rational granularity level, refined chromium drainter is suitable for the long steelmaking process of LF, VD, Rh and other refined steelmaking techniques. ; Stainless steel chromium drainter is suitable for stainless steel series steel types; thin plate drainters are suitable for thin plate steelmaking processes on various sections. Adopt advanced production technology scientific formulation. It has the characteristics of high natural pouring rate (more than 98 % under normal conditions), strong adaptability, long time (3-4 hours), and reasonable price.
Due to the long time of turning in the iron water bag, the temperature loss is serious. To solve this problem, iron bag coverage. Scope of adaptation: This product adapts to the drainage of mold casting, continuous casting and sliding water inlets of cast steel. Variety: According to different steel species and casting self -rate, the product is divided into two series: silicon drainage sand and chromium drainage sand.
Chrome drainage sand is often in high temperature in the steel forage water outlet for a long time, so the fire resistance is high. Because the drainage sand is filled in the water inlet and directly received the steel. Therefore, the sintering temperature should not be too high; in order to prevent the role of huge steel water in the process of use and prevent the shed, the quantitative lubricant needs to be added, thereby reducing the friction between the drainage sand particles.
