Embodiment 1

[0049] A high-temperature baffle brick formed by machine pressing of the present invention is made of a base material and a binder. The base material is calculated by weight: 60% of high alumina material, 10% of mullite material, and 10% of Guangxi white clay. % and corundum powder 20%, the binder is composed of 30% of 180 mesh mullite material, 20% of 180 mesh high alumina material and 50% of water, the binder is added to the base material by weight as the base material 10% by weight (ie base material: binder = 100:10 or written as 10:1).

[0050] Such as 1000kg of base material, including 600kg of high alumina material, 100kg of mullite material, 200kg of corundum powder and 100kg of white clay, the binder is composed of 30kg of mullite material, 20kg of corundum powder and 50kg of water, that is, the baffle brick is composed of 1000kg It is made of materials composed of the base material and 100kg of binder.

[0051] The production method that realizes embodiment 1 is, at ...

Embodiment 2

[0053] A machine-pressed high-temperature baffle brick of the present invention can also be composed of a base material composed of 55% of high-alumina material, 12% of corundum powder, 18% of mullite and 15% of white mud by weight: Mo It is made of a binder consisting of 30% of stone powder, 30% of corundum powder and 40% of water. The amount of binder added is 12% of the base material. It is composed of 1800kg of stone and 1500kg of white clay, and the binder is composed of 360kg of mullite powder, 360kg of corundum powder and 480kg of water. The process step of present embodiment 2 is the same as embodiment 1.

[0054] Because the components of the baffle bricks produced by the machine press molding method of the present invention are different from those of the traditional cast-molded baffle bricks, the components are scientific and reasonable, and the binder does not use existing lignin or simple water, and is made at 1480°C It is fired at a high temperature above -1580°...

Abstract

The invention relates to a production method of a mechanically press-molded high-temperature baffle brick. The method comprises the following steps: (1) a raw material is prepared; (2) a mold is mounted; (3) the prepared raw material is added into the mold; (4) pressure vibration is carried out with a vibration molding machine, wherein a work bench of the vibration molding machine performs high-frequency vibration under the driving of a motor, and at a same time a hydraulic pressure head applies forces to the raw material in the mold under the push of a hydraulic cylinder; (5) mold release is carried out; (6) an obtained baffle brick blank is fired in a high-temperature kiln; and (7) sorting and packaging are carried out. With the method for producing the high-temperature baffle brick through mechanical press molding, production efficiency can be greatly improved, and the produced baffle brick has high refractoriness and good thermal stability. Therefore, problems of low production efficiency, low refractoriness and poor thermal shock resistance of existing baffle bricks are effectively solved.

Description

technical field [0001] The invention relates to a production method of machine-pressed high-temperature baffle bricks, belonging to the field of refractory material manufacturing. Background technique [0002] The rapid development of science and technology provides a great opportunity for the development of steel rolling technology to save energy, reduce consumption, and prolong the longevity of heating furnaces. As a result, the demand for regenerative heating furnace lining materials is increasing. Due to the harsh working conditions of the heating furnace burner bricks, pipe bricks, hot air outlets and other parts, the frequent alternation of cold and heat (thermal shock phenomenon), the impact on these parts Refractory materials are more destructive, so the life of the heating furnace is closely related to these refractory materials. [0003] At present, the regenerative burner (RCB) produced by my country's refractory enterprises is a burner that recovers heat from ki...
