Abstract

The present invention provides a kind of molybdenum carbon silicon combined high temperature refractory materials that can be suitably used for kiln, waste incinerator and boiler furnace, can be at 1400 DEG C --- under 1600 DEG C of working temperatures, it do not crack, not avalanche, generate phenomena such as melting drop, be able to maintain the stable state of inboard wall of burner hearth.

Description

Molybdenum carbon silicon combined high temperature refractory material
Technical field
The present invention is a kind of mode for being related to improving existing high-temperature refractory.It is suitable for kiln, waste incinerator and pot The high-temperature refractory of furnace burner hearth.
Background technique
The burner hearth of existing kiln, waste incinerator and boiler, mostly using containing aluminium imitate high refractory fireclay block (be commonly called as: Alumina firebrick) code builds, the melting drop that cracking, avalanche and high temperature generate due to caused by being expanded with heat and contract with cold, so that institute With the lost of life of burner hearth, to influence production efficiency, and the raising of production cost is caused.
Summary of the invention
Molybdenum carbon silicon combined high temperature refractory material of the invention, can be 1400 DEG C in firing space behavior temperature --- 1600 DEG C of high temperature Under, it does not crack, not avalanche, generate phenomena such as melting drop, so that inboard wall of burner hearth is kept whole complete, to improve the use of burner hearth Service life.
Embodiment
Molybdenum carbon silicon combined high temperature refractory material prescription of the invention and chemical analysis are as follows:
70% feldspar in powder (K of silicon carbide (SiC)2O-Al2O3-6SiO2) 5%
Molybdenum powder (MO) 25%
It by above-mentioned all raw materials, is equipped in its ratio, is stirred two hours into blender, mix them thoroughly Hou Jiashui, The moisture ratio humidity of mixture is 10% or so, and the mixture that will be mixed is sent into molding steel die, and use is not small In 500 ton large-scale hydraulic presses, it is pressed into the blank of component needed for burner hearth, kiln is entered after drying and is sintered, sintering temperature 1450 DEG C high temperature, the time keep two hours or so it is constant, make the green body of its component at high temperature, adequately sintering forms stable change Structure is learned, after kiln natural cooling, component can be taken out and be used for required burner hearth.This is arrived, the compound height of molybdenum carbon silicon of the invention Warm refractory material, narration finish.
