Description
Technical field
The present invention relates to fire resisting material fields, and in particular to a kind of chamotte and preparation method thereof for being bonded containing carbon brick.
Background technique
Fire clay, also known as chamotte, the puzzle joint material as refractory product masonry, mainly by refractory powder, bonding agent and outer
Agent is added to form.The construction method that ladle is built is that the smooth magnesia carbon brick in surface is built layer by layer, is then glued from level to level with chamotte
It picks up and, so that refractory brick and chamotte is combined into an entirety by sintering.
What is used currently used for chamotte of the bonding containing carbon brick is all magnesia chamotte or magnalium chamotte, uses water as combination
Agent, this allows for chamotte and shrinks at high temperature larger, and biggish contraction leads to risk there are bleed-out, at the same magnesia chamotte or
The poor water retention property of magnalium chamotte causes the construction time of chamotte that cannot reach the requirement of steel mill sometimes.
Intensity is low after common chamotte is burnt, and is especially bonded when containing carbon brick, and common chamotte is very poor to the cementability containing carbon brick,
Almost without intensity under high temperature, once having loosening containing carbon brick, common chamotte can not provide the fixed intensity containing carbon brick.
Summary of the invention
The present invention provides a kind of chamotte for being bonded containing carbon brick, have good ductility, mobility and cementability,
It is appropriate to be bonded the time, and is bonded when containing carbon brick with good intensity.
The parts by weight of raw materials composition of a kind of chamotte for being bonded containing carbon brick, the chamotte is as follows:
Chamotte provided by the invention, raw material are easy to obtain, and preparation method is simple, and prepared chamotte has good extension
Property, mobility and caking property, bonding when containing carbon brick, is with good intensity.
The vanadine particle preferably uses superfine vanadine particle.The mass fraction of aluminium oxide is not less than in the vanadine particle
85%.Further preferably, the partial size of the vanadine particle is 1~0.088mm.
Preferably, the carbon containing resinoid bond is furane resins.Further preferably, the viscosity of the furane resins is
1000~15000mPas.The solid content of the furane resins is 55~60%, and Residual carbon is 30~33%.
Preferably, the partial size of the corundum fine powder is 150 mesh~325 mesh.The partial size of the magnesia powder be 150 mesh~
325 mesh.The partial size of the alumina powder is -320 mesh.The i.e. described alumina powder can pass through 320 meshes.
In the present invention unless otherwise specified, mesh number is all made of Taylor system.
Preferably, the parts by weight of raw materials composition of the chamotte is as follows:
Further preferably, the parts by weight of raw materials composition of the chamotte is as follows:
The present invention also provides a kind of preparation methods of chamotte, and each raw material is mixed according to weight
It arrives.
Provided by the present invention for being bonded the chamotte containing carbon brick, there is good ductility, mobility and cementability, bonding
Time is appropriate, and is bonded when containing carbon brick with good intensity.
