The steel plant produces 3.4 million tons of steel annually, but it is currently unable to produce at full capacity. The slab workshop has 4 electric furnaces, 4 refining LF furnaces, and 3 2-machine 2-stream slab continuous casting machines. 200-ton ladle and 25-ton tundish. T
here, you can find the most drawing of slide gate plate,such as 1qc,2qc,cs60,ft160 slide gate plate,LG series，flocon 4200,6300 slide gate plate
In CC practices, the gas shrouding and mechanical shrouding have been usually combined, that is injecting argon into a ladle shroud to improve the shrouding performance.Argon can be injected from the shroud neck as shown in Fig. 5(a), which has been widely used. An argon curtain is fixed around the head of the shroud in
In the realm of modern steel manufacturing, thin-slab continuous casting machines (CCMs) have revolutionized production by enabling the creation of ultra-thin (50–150 mm) and high-quality steel slabs at unprecedented speeds (up to 8 m/min). Central to the success of this process is the submerged entry nozzle (SEN)—a precision-engineered component that bridges the tundish and mold,
In order to guarantee the successful application of slide gate plate (include upper nozzle, top plate, middle plate, bottom plate and lower nozzle; We would like to provide the following information for us to better understand the operation condition. Investigation item Content Name of Steel mill 钢厂名称 Steel smelting method: By EAF, Converter or
No. Questions Answer 1 Name of melt shop 冶炼车间名字 2 Steel grade 钢种 3 Capacity of ladle 钢包容量 4 The temperature range of molten steel in Ladle 钢包中钢水的温度范围 5 Casting time per heat 浇钢时间 6 The time needed to shift another heat 换包时间 7 Capacity of tundish 中包容量 8 The temperature range of molten steel
During tapping of liquid steel through slide gate, the steel is passing through the slide plates and hence is subjected to the attack of slag and liquid infiltration in contact surface. Since it is in contact with molten steel at high temperature, high hot strength is required. In closed condition, the ferro-static load is also
slide gate plate is very important refractory in the steel making.So, we should know the reason for the wear after usage.
