Description
Technical Field
The invention belongs to the field of refractory kiln furniture preparation, and particularly relates to a volume-stable high-temperature bedplate and a manufacturing method thereof.
Background
The bedplate, also called push plate or moving plate, is a key part for carrying the propelling operation of products in the push plate kiln, not only needs to meet the high-temperature atmosphere condition of sintering, but also needs a thin bedplate (generally with the thickness of only 30mm) to bear the pressure of 20-30 kg/plate and transmit the propelling extrusion force of the burnt products for a long distance (about 30M), and the bedplate can bear the constantly changing impact of high and low temperature (once circulating in the furnace every 20-30 h) caused by long-term circulation from room temperature → high temperature → room temperature), and has long service life. When the push plate is used, if only one push plate is broken, falls off and climbs the plate, is bonded or deforms, the push plate can cause a serious accident that the push plate cannot be continuously pushed and is forced to be stopped for carrying out the top turning treatment, and great economic loss is caused to a user. Therefore, the bedplate not only needs to have excellent high-temperature resistance and wear resistance, and better thermal shock resistance stability and volume stability, but also needs not to pollute a fired product, ensures the consistency of the bedplate, and has extremely high requirements on the comprehensive performance of the bedplate.
At present, mullite platens are usually used in the market, platens made of other materials such as cordierite and corundum are not suitable for expansion due to low refractoriness, and silicon carbide is not suitable for expansion due to oxidation resistance in an oxidizing atmosphere, for example, a push plate for a nitrogen kiln sintered by soft magnetic ferrite of Chinese patent CN1796465 comprises, by weight, 0.5-3mm 40-45% of electrofused mullite, 0.06-0.5mm 5-8%, less than 0.04mm 18-22%, 0.5-3mm 8-12% of tabular corundum, 0.06-0.5mm 1-3% of electrofused white corundum, α -alumina less than 0.045mm 10-14%, less than 4um 4-6%, 2-4% of silica powder and 8-9% of silica-alumina gel, and the soft magnetic ferrite sintered nitrogen kiln is suitable for being used in a nitrogen kiln below 1450 ℃, and the temperature and the requirements of the push plate are different from those of the present patent, and the present invention is greatly different from that of the present patent.
Chinese patent CN201410809937.3 is a high-performance modified mullite high-temperature platen and a preparation process thereof, wherein the weight percentages of the modified mullite high-temperature platen are that fused mullite is less than or equal to 3mm and 40-50%, tabular corundum is less than or equal to 3mm and less than or equal to 3-35%, α -alumina is less than or equal to 320 meshes and 12-20%, spinel is less than or equal to 200 meshes and 3-5%, kaolin is less than or equal to 200 meshes and 7-10%, and a lanthanum oxide and yttrium oxide composite rare earth additive is less than or equal to 1um and 0.5-1%, and the mass ratio of yttrium oxide to lanthanum oxide in the lanthanum oxide and yttrium oxide composite rare earth additive is 1: 0.05-0.3.
Disclosure of Invention
The invention aims to provide a volume-stable high-temperature bedplate, which is a key part for pushing and operating various electronic materials and special ceramic products with the temperature below 1600 ℃ to be sintered in a push-plate kiln as a bearing product, and is mainly characterized in that an aluminum titanate material with low expansion coefficient, high thermal shock resistance and excellent thermal shock resistance is introduced into the field of bedplate kiln furniture, and the introduced aluminum titanate material is subjected to composite second phase doping modification, so that the problem of high temperature instability of the aluminum titanate material at 800-1300 ℃ is effectively solved, namely, a small amount of silicon oxide and mullite micropowder is added into the composite refractory material system, a stable solid solution is formed under high-temperature firing, the crystalline phase of the formed solid solution has a decisive effect on inhibiting the high-temperature decomposition of the main crystalline phase of aluminum titanate, the volume stability of a composite material product can be ensured, meanwhile, the mullite composite second phase formed by the reaction in the solid solution can improve the high-temperature strength and the high-temperature thermal shock resistance of the composite material.
The bedplate which is made by using sintered corundum and fused mullite particles as aggregates and introducing an aluminum titanate composite phase material into a matrix and firing at high temperature can meet the requirements of high-temperature strength and good thermal shock property in use, and can also obviously improve the volume stability of the bedplate, and the size change in the pushing direction is less than or equal to 0.5 percent after long-time circulation in a use environment.
The method is implemented specifically as follows: a volume-stable high-temperature bedplate is characterized by comprising the following raw materials in percentage by mass:
30-40% of sintered corundum with the thickness of 1-3 mm
0.3-1 mm 10-20% of electrically-fused mullite particles
α -alumina micropowder is less than or equal to 0.045mm and 15-25%
The content of the electrically fused mullite micro powder is less than or equal to 0.045mm and is 10-20%
The aluminum titanate micro powder is less than or equal to 0.063mm and is 10-20%
The content of the silicon dioxide micro powder is less than or equal to 0.045mm < 2 > -6%
5-10% of kaolin with the diameter less than or equal to 0.063 mm.
The manufacturing method of the volume stable type high temperature bedplate comprises the steps of firstly, adding 0.1% of polyvinyl alcohol organic binder aqueous solution on the electric melting mullite micro powder, the aluminum titanate micro powder and the silicon dioxide micro powder on a ball mill according to the proportion, performing ball milling to prepare slurry, performing dry powder granulation, adding the sintered corundum, the electric melting mullite particles, the α -alumina micro powder and the kaolin into a V-shaped mixer according to the mass percentage, adding the granulated material into the mixer, uniformly mixing, sealing and ageing for 30-48 hours, performing pressure molding on a large-tonnage press, drying, and then performing high temperature sintering to prepare the volume stable type high temperature bedplate.
The main reason for causing the damage of the high-temperature bedplate is the contradiction between the thermal shock resistance and the mechanical strength, and the bad thermal shock resistance can cause the bedplate to crack or break and damage due to the cold and hot cyclic impact which cannot start cold and hot sudden change; the mechanical strength is not enough, delamination, chipping and stripping can be generated under the alternate firing environment, and the bedplate can be cracked or broken seriously; in addition, poor volume stability of the high-temperature bedplate is also a main reason for short service life of the high-temperature bedplate; on the basis of fully mastering the main reasons of the bedplate, such as the use environment requirement, the damage and the short service life, the invention introduces the aluminum titanate material and critically introduces the doping modification of the composite second phase of the aluminum titanate material to form a stable solid solution under high-temperature sintering, so that the volume stability of a composite material product can be ensured, and simultaneously, the high-temperature strength and the high-temperature thermal shock resistance of the composite material can be improved by the mullite composite second phase formed by the reaction in the solid solution.
