Production mold of small prefabricated block for refining ladle and using method thereof

Abstract

The invention discloses a production die for a small precast block used for refining a steel ladle and a use method of the production die and belongs to the field of refractory materials. The die comprises a die bottom plate, two longitudinal end die plates, two transverse end die plates, at least one transverse partition plate and multiple longitudinal insertion plates. The die bottom plate is a square plate, and a center working area of the bottom plate protrudes. The longitudinal end die plates are rectangular equal-thickness plates, the cross section of each longitudinal end die plate is in a rectangle shape or a parallelogram shape, through grooves in the vertical direction are formed in the faces, facing die cavities, of the longitudinal end die plates, and the two ends of the transverse partition plates are embedded in the grooves. The transverse end die plates are L-shaped equal-thickness plates, the faces, facing the die cavities, of the transverse end die plates are evenly provided with oblique grooves, the two ends of the longitudinal insertion plates are embedded in the oblique grooves, and a positive splayed and reverse splayed alternative structure is formed. According to the production die and the use method, the die does not need to be loaded or unloaded complicatedly, and continuous production of the precast block is achieved; and the structure is compact, grout escaping and leaking are not likely to happen, and the product quality is improved.

Description

technical field [0001] The invention relates to a production mold of a small prefabricated block for refining ladles and a use method thereof, belonging to the field of refractory materials. Background technique [0002] Among the lining materials of the refining ladle, the working lining of the ladle built with small prefabricated blocks has a good thermal insulation effect, can effectively reduce the temperature drop of the molten steel during the refining process, and can effectively prevent the carburization of the molten steel. It is beneficial to the production of low carbon steel and clean steel. Prefabricated blocks are easy to build, high in construction efficiency, and long in service life. Therefore, many domestic refractory companies have tried the production and use of prefabricated blocks, but they have not yet formed a good situation for large-scale application. The reason is that small prefabricated blocks are difficult to promote and use on a large scale, m...

AI Technical Summary

Problems solved by technology

Although the small prefabricated block is small in size, it is also necessary to disassemble each part of the mold for demoulding operation. After the demoulding is completed, the mold is assembled in a certain order, and then each screw and bolt is fastened. The operation steps are complicated and cumbersome, the production efficiency is low, the production capacity is limited, and the labor cost is too high
