Embodiment 2

[0103] Such as figure 1 , 2 As shown in and 15, a preparation process for high-strength magnesia-carbon bricks for refining ladles comprises the following steps:

[0104] Step 1, the upper mold 32, the mold circulation device 3 transports the mold 32 to the mold cavity assembly 22 in the first pressing device 1, and the mold 32 is introduced into the mold cavity assembly 22 by the mold introduction assembly;

[0105] Step 2, adding powder, the die assembly 23 continues to rise to drive the powder adding device 4 to open the mold cavity 223 to add powder;

[0106] Step 3, primary pressing, the die assembly 23 descends to perform the first pressing on the powder;

[0107] Step 4, secondary pressing, the die assembly 23 rises, drives the rack frame 2411 to drive the cleaning wheel set 25 to move, and the cleaning wheel set 25 drives the gripper 2424 to move to clean and collect the excess powder on the outer column 221 mouth to the auxiliary adding assembly 42 , when the die a...

Abstract

The invention relates to preparation equipment and process of a high-strength magnesia carbon brick for a refining ladle. The equipment comprises a first pressing device, a second pressing device which is arranged on one side of the first pressing device, a mold circulation device and a powder adding device, the first pressing device and the second pressing device each comprise a rack, a mold cavity assembly, a pressing mold assembly and a transmission assembly and further comprise a mold leading-in assembly; and the process comprises the procedures of mold feeding, primary pressing, secondarypressing, transferring and overturning, reverse side pressing and discharging. The first pressing device and the second pressing device are arranged to press and form the front face and the back faceof powder, transferring and overturning a mold is realized over between the first pressing device and the second pressing device through a second transmission unit, and automation of mold feeding, primary pressing, secondary pressing, transferring and overturning, reverse side pressing and discharging is matched, so that automatic production is achieved, forward and reverse pressing of bricks isachieved, pressure is balanced, and the compaction degree of refractory brick pressing is uniform.

Description

technical field [0001] The invention relates to the technical field of refractory material processing, in particular to equipment for preparing high-strength magnesia-carbon bricks for refining ladles and a process thereof. Background technique [0002] my country is the world's production base of refractory bricks, and the domestic and international market demand has broad prospects. my country already has perfect professional technology and production technology for refractory bricks, but it lags far behind developed countries in the development of automatic production equipment for refractory bricks. Most of the domestic Manufacturers mainly use pure manual operation equipment or semi-automatic equipment, and often operate manually in terms of feeding and output of bricks after forming; while manual feeding mostly uses experience to judge the amount of raw materials required for individual bricks, which leads to its work efficiency. , and the product quality is low; it is m...
