Abstract
The invention discloses a sink head brick, comprising the following raw materials of: 30wt%+/-5wt% of cordierite, 20wt%+/-5wt% of aluminium titanates, 15wt%+/-5wt% of synthesis mullite, 15wt%+/-5wt% of wood chip and 20wt%+/-5wt% of polyester ball. The invention also provides a processing technology of the sink head brick. The sink head brick provided by the invention is characterized in that it has advantages of high-temperature resistance, low heat-conduction coefficient, high insulation, strong heat-insulation performance, light weight, and convenient installation; it can raise casting quality and reduce production cost; it has strong anti-metal liquid erosion capability; it can not be burned; it dose not adhere to sand and contains no binder; it does not react with molten steel and not destroy characteristics of molten steel tissues.
Description
Technical field
The present invention relates to a kind of sink head brick and complete processing thereof.
Background technology
On the rising head of the steel casting of large-scale high added value such as nuclear power, wind-powered electricity generation, defence and military, the sand rising heads that adopt more, thermal insulation is poor, thermal conductivity is too high, preponderance, increase workman's labour intensity is unstable in the riser feeding process during installation, not in place and the feeding defective of feeding affects the inner quality of foundry goods.
Summary of the invention
Problem to be solved by this invention just provides simple, the easily manufactured sink head brick of a kind of technique and complete processing thereof, and high temperature resistant, thermal conductivity is low, high insulation, and thermal insulation is strong, and is lightweight, easy for installation.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of Novel sink head brick, it is characterized in that: comprise that raw material composition by weight percentage is as follows, cordierite 30% ± 5%, aluminium titanates 20% ± 5%, mullite synthesizing 15% ± 5%, wood chip 15% ± 5%, polyester pellet 20% ± 5%.
Further, described wood chip is poplar bits or pine sawdust.
A kind of complete processing of Novel sink head brick also is provided in addition, it is characterized in that: may further comprise the steps,
1) adopts the above-mentioned raw materials composition after mixing, stirring, to put into pressing mold and be pressed into adobe;
2) adobe is sloughed free-water through drying in the shade, dry, dry three process;
3) adobe is sloughed and is put into the low temperature oven heating behind the free-water and slough crystal water;
4) the High Temperature Furnaces Heating Apparatus calcining of packing into behind the crystal water is sloughed in adobe, forms the work in-process brick behind the furnace cooling;
5) the work in-process brick forms finished bricks after cutting, polishing.Here be to cut according to the customer requirement size.
Further, the time that described adobe is dried in the shade is 8～12 hours, and the time that adobe is dried is 4～8 hours, and the time that adobe is dried is 1～2 hour.
Further, Heating temperature is 200～300 ℃ in the described low temperature oven, and be 1～2 hour heat-up time.
