Embodiment Construction

[0028] A magnesia heating brick, characterized in that: the weight percentage of each component of its constituent raw materials is:

[0029] Fused magnesia 40-50%

[0030] Sintered magnesia 40-50%

[0031] Silica powder 2-4%

[0032] Kaolin 4-6%

[0033] Binder 1-3%.

[0034] The production method of the described magnesia heating brick is characterized in that: it specifically comprises the following steps:

[0035] (1) Break the blocky material;

[0036] (2) Pass the crushed particles through a vibrating sieve, requiring the particle size to be less than 5mm, and returning large particles to continue crushing and sieving;

[0037] (3) 75-80% magnesia powder after crushing is put into the mixer as aggregate, and then the binder is put into it for premixing for 2-4 minutes;

[0038] (4) Mix the remaining magnesia powder and silicon micropowder evenly, then put the mixture into the mixture of step (3) and continue mixing for 30-40 minutes;

[0039] (4) pressure molding ...

Abstract

The invention provides a magnesium heating brick which comprises the following raw materials by weight percent: 40-50% of fused magnesia, 40-50% of sintered magnesia, 2-4% of silicon micropowder, 4-6% of kaolin and 1-3% of binding agent. The production method of the heating brick comprises the following steps: crushing and sieving blocky raw materials; mixing with powdery materials; adding the binding agent for mixing; carrying out pressure forming; feeding the formed material into a dry kiln for drying; grinding; qualifying; packaging; and warehousing. The material provided by the invention can be installed in electric heater equipment to realize fast heat absorption, long heat storage time and slow heat release, thereby achieving good heating and energy-saving effects.

Description

technical field [0001] The invention relates to the field of production and processing of refractory materials, in particular to a non-burning magnesia heating brick and a production method thereof. Background technique [0002] Most areas in China are relatively cold in winter, and gas is mostly used for heating, and the heating time is short and the cost is high. Burnt magnesia bricks are usually installed in current heating equipment as heat storage and heat release materials, but the production cycle of magnesia bricks is long, the cost is high, the density of magnesia bricks is high, the weight is heavy, the firing temperature is high, and the environmental pollution is serious. Contents of the invention [0003] The invention provides a non-burning magnesia heating brick and its production method. The magnesia heating brick of the invention is installed in the electric heater equipment, which can absorb heat quickly, store heat for a long time, and release heat slowl...
