Refractory brick forming method with multidirectional force application characteristic and auxiliary device thereof

Abstract

The invention discloses a refractory brick forming method with a multidirectional force application characteristic and an auxiliary device thereof. The method comprises the following steps: step 1, guiding a mixture which is uniformly stirred in a mixing mill into a mold of a brick press, starting the brick press to apply pressure to the mixture in the mold for the first time until a pressing block moves downwards and stops, then moving the pressing block upwards, and jacking a green body which is pressed for the first time out of a mold frame to the position of a forming tabletop by a brick jacking device at the lower part of the mold; step 2, turning over a green brick subjected to primary light pressing, specifically, clamping the two ends of the green brick subjected to primary pressing by adopting an auxiliary refractory brick turning device, upwards moving the green brick to a certain height by clamps in a clamped state, starting a turning action, and turning over the green brick by taking a connecting line of centers of the two clamps as an axis. According to the refractory brick forming method with the multidirectional force application characteristic provided by the invention, refractory bricks are processed by adopting a light pressing-overturning-light pressing method, so that the mixture has better compactness, the probability of generating layer cracks in the finally formed bricks is greatly reduced, and the rate of finished products and the yield of products are improved.

Description

technical field [0001] The invention belongs to the technical field of refractory brick processing methods, and in particular relates to a refractory brick forming method with multi-directional force application characteristics and an auxiliary device thereof. Background technique [0002] At present, the forming methods of shaped refractory materials are all semi-dry forming, that is, the aggregate and fine powder are added with a binder (usually phenolic resin) and then stirred evenly in the mixer until the material has a certain degree of plasticity, and then poured into the mold after discharge. , and then pressed into shape under a certain pressure. According to the model used and the specific pressing mode, it is divided into two categories. One is hydraulic press forming. After the mixture is poured into the mold, it is pressed and formed by hydraulic pressure at one time to achieve the required density. The investment in hydraulic press equipment is large and the ma...

AI Technical Summary

Problems solved by technology

In multiple press forming, although the pressing mode of light first and then heavy has been adopted, spallation is still the main reason for the scrapping of the green body

Moreover, this forming system also has corresponding requirements on the dryness, wetness and plasticity of the mixture. The fluctuation of the above-mentioned process parameters in this forming mode is likely to cause problems such as low unit weight and aggregate crushing, which is not good for the performance of the final product.
