Embodiment Construction

[0023] Such as figure 1 Shown, the production method of light insulation heat-resistant refractory brick of the present invention, comprises the steps:

[0024] (1) Using biomass materials to brew waste residues including wine residues, vinegar residues, sugar residues, sauce residues and plant straws including barley straw, sorghum straw, rice straw, and oat straw;

[0025] (2) According to different processing methods, make it obtain particle size, humidity, resilience and other properties in line with the requirements of the pore-forming material index;

[0026] (3) Coordinate the above-mentioned materials with the semi-raw minerals of the coal mine according to a certain ratio, send them into the mixer and add water to mix them into mud;

[0027] (4) Place the mud material for a certain period of time to trap the material, so that the moisture in the batch material is fully uniform;

[0028] (5) extrude the wet billet that contains certain moisture with the different len...

Abstract

The invention provides a production method of a light insulating heatproof firebrick. The production method comprises the following steps of 1, selecting biomass material brewage waste residues such as vinasse, vinegar residues, sugar residues and sauce residues and plant straws such as barley stalk, sorghum straws, paddy straws and oat straws, 2, by different processes, treating the biomass material brewage waste residues and the plant straws so that performances such as granularity, humidity and resilience satisfy pore-forming material index requirements, 3, blending the above material and associated minerals in coal mine according to a certain ratio, feeding the mixture into a blender, adding water into the mixture and carrying out mixing to obtain slurry, 4, standing the slurry for a certain time for mixture ageing so that water in the mixture is fully and uniformly distributed, 5, extruding the mixture by an extrusion molding machine to obtain wet blanks having different cross sections, different lengths and a certain water content, 6, drying the wet blanks to obtain dry blanks having a certain water content, and 7, carrying out pre-heating and sintering on the dry blanks in a calcining kiln and cooling the sintered dry blanks to obtain the light insulating heatproof firebrick.

Description

technical field [0001] The invention relates to a production method of fire bricks, in particular to a production method of light-weight insulating heat-resistant fire bricks. Background technique [0002] With the increasing scarcity of energy materials and mineral resource materials, the contradiction between the supply and demand of pore-forming agent materials used to manufacture lightweight heat-insulating refractory bricks has become increasingly acute. The development of easy-to-obtain low-value substitute raw materials is undoubtedly of great practical significance for manufacturers of mullite lightweight heat-insulating refractory bricks. Porogen materials are one of the important raw materials for the production of lightweight mullite insulation refractory bricks. [0003] Traditional lightweight insulation brick pore-forming materials include coal powder, sawdust, and foamed plastics that have been commonly used in recent years. Coal powder can only be used in t...
