Ultra-large high-strength cooling die for refractory castables

Abstract

The invention relates to the technical field of castables, and discloses an ultra-large high-strength cooling die for refractory castables. The cooling die comprises a machine box, a cooling-water machine and a water tank. The machine box is internally provided with a support plate, the upper surface of the support plate is connected with a cooling die body through bolts. According to the ultra-large high-strength cooling die for the refractory castables, the castables are placed in the cooling die body, a first cylinder is arranged and pulls the support plate through a rack so as to drive thecooling die body to move towards the inside of the machine box, and the rack drives a first thread rod and a second thread rod to rotate through a gear. As the directions of threads of the first thread rod and the second thread rod are opposite, two threaded sleeves move relatively, two first water bags are driven to move relatively, and the two first water bags are attached to the side wall of the cooling die body. Through the arrangement of the cooling-water machine and a water pump, cooling water in the water tank flows into the first water bags and a second water bag through a second water pipe, connecting water pipes and a third water pipe, and the cooling die thus has a uniform and rapid cooling effect.

Description

technical field [0001] The invention relates to the technical field of castables, in particular to a cooling mold for super-large-volume, high-strength castables. Background technique [0002] Castable is a granular and powdery material made of refractory material, and it is composed of a certain amount of binder and water. With high fluidity, it can be constructed by pouring method when used, and it is an unshaped refractory material that can be hardened without heating. It is composed of refractory aggregate, powder, binder, admixture, water or other liquid materials. [0003] The existing cooling molds for castables on the market are often cooled by winding cooling water pipes on the outer surface of the mould, and cooling is carried out through water circulation. There are gaps between them, so that the mold cannot be cooled uniformly, and the cooling efficiency is low. The conventional technical process is complex and the cost of the measures is high. The control pri...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a cooling mold for super-large-volume high-strength castables, which has the advantages of rapid cooling and uniform cooling of the mold, synchronous cooling inside and outside the mold, reduces the temperature difference between inside and outside, reduces cracks, and solves the need for cooling water pipes The quantity is large, and the winding and installation of the cooling water pipe is inconvenient, the mold cannot be cooled evenly, and the cooling efficiency is low
