Refractory Brick Powder Hydraulic Press - How Are Refractory Bricks Made?

Refractory bricks are made of refractory materials, sand, fly ash, stone powder, gravel, construction waste, cement, etc. Shuntec Press has designed and produced a refractory brick powder hydraulic press, with a three-beam and four-column structure or four-beam four-column structure, which can process various silica bricks, high alumina bricks, magnesia calcium bricks, magnesia carbon bricks, magnesia bricks, and other refractory bricks with molds. Refractory bricks are widely used in high-temperature industries such as iron and steel smelting, building materials, non-ferrous metals, and chemicals.

The processing of refractory bricks is generally carried out through the cooperation of the pressure of the refractory brick powder forming hydraulic press and the mold. The specific parameters of the press can be based on customer requirements, such as tonnage, stroke, daylight, bed table size, and processing speed. It can be adjusted in ways such as the number of extra bricks in one mold.

According to the material, specification, density, etc. of refractory bricks, Shuntec Press can design and build 630 tons, 800 tons, 1200 tons, 1500 tons, 2000 tons, and other different tonnages of refractory brick powder compacting hydraulic presses for customers. Cooperating with automatic supporting devices such as automatic feeding devices, brick push-out devices, transfer devices, etc., we can realize the fully automatic operation of refractory brick production.

The refractory brick powder molding process

  1. Raw material crushing: The refractory material is then fed into the crusher and filtered through the screen. The raw materials with a particle size larger than 3mm need to enter the mill to be ground into a fine powder and transported to the silo.
  2. Kneading: The refractory materials are weighed according to the scientific ratio, and then added to the wheel mill to mix evenly, statically mixed for 15 minutes, and there must be no mud and dry materials in the mixing material.
  3. Forming: The mixed material is sent to the hopper through the transmission belt, and the quantitative mixture is sent into the mold after weighing, and after being rapidly pressed and formed by the refractory brick powder forming hydraulic press, it is sent to the brick output belt, and then palletized to the kiln car by the automatic palletizing machine.
  4. Sintering in the kiln: The stacked kiln car is sent into the kiln by the tractor, and after high-temperature sintering, high-temperature resistant bricks can be realized.

The refractory brick powder hydraulic press generally adopts a vertical four-column, two-way pressurizing structure, driven directly by the oil pump. It can realize two-way equal-quantity pressing, low and high-pressure multiple pressurizations, and stable pressure forming, and is equipped with a volume feeding device, product clamping and conveying device, and automatic adjustment device for brick thickness, which can meet various requirements of refractory material forming process. Loading-forming-bricking, the entire production process is fully automated.
