Abstract
The invention discloses a high thermal state breaking strength high alumina prefabticated member containing simple substance silicon. A preparation method of the prefabticated member is that the prefabticated member considers bauxite chamotte, the simple substance silicon and a binding agent as base materials, firstly a dispersing agent is added in the three base materials to be evenly stirred and mixed in a dry mode, then water is added to be evenly mixed the evenly-mixed materials to inject in a mould for vibration moulding, maintenance are carried out after moulded, the prefabticated member is roasted in a roasting kiln, the roasted prefabticated member is then roasted at high temperature and cooled to reach the room temperature after sintered to obtain the high thermal state breaking strength high alumina prefabticated member containing the simple substance silicon. The high thermal state breaking strength high alumina prefabticated member solves the problem that a common high alumina prefabticated member is poor in high-temperature behavior and high-temperature volume stability and the like and improves normal temperature strength, and the product of the high thermal state breaking strength high alumina prefabticated member has better high-temperature behavior, thermal shock stability and volume stability than the common high alumina prefabticated member.
