A kind of up and down pressure refractory hydraulic forming machine and one-time forming method thereof

Abstract

The invention provides an up-down pressing fireproof material hydraulic forming machine. An upper die is pushed through an upper oil cylinder, and a lower oil cylinder pushes a lower die to achieve bidirectional pressing forming of fireproof materials. The invention further provides a one-time forming method of fireproof materials with shells through the fireproof material hydraulic forming machine. The method includes the following steps that a metal shell is placed in a die cavity of the fireproof material hydraulic forming machine; an upper feeding sleeve is combined to the die cavity through a connection piece in a covering mode; raw materials are put into the die cavity, and the up-down pressing fireproof material hydraulic forming machine is made to work; a finished product is taken out after demolding is conducted. By means of the one-time forming method of the fireproof materials with the shells, the generation and forming process of the fireproof materials with the shells is simplified, manpower input and man-made defects are reduced, the consumption of fireproof batches is eliminated, efficiency is improved, the cost is saved, and meanwhile the quality of products is guaranteed.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a one-time forming method and equipment for refractory materials with shells. Background technique [0002] like figure 1 As shown, when producing refractory materials such as sewer bricks for steelmaking, a metal shell needs to be put on the outside of the refractory material. After applying the refractory mud, put the metal shell on, strictly control the position of the metal shell relative to the drain brick, and then transfer it to the drying room to dry the refractory mud. [0003] This process method is purely manual operation with high labor intensity, and the filling rate of refractory mud is affected by the factors of the operator, and the error is relatively large. In addition, a special drying process needs to be set up in the process, which increases the workload and process time, and the production efficiency is low. Contents of the invention [000...
