Description

A kind of high-temperature enamel
Technical field
This application involves the enamel that a kind of glassed steel and its surface use.
Background technology
The quick-fried phenomenon of squama is to cause the major reason of glassed steel high rejection rate, and fish scaling resistance is to weigh glassed steel enamel property Important indicator.Cause enamelware produce squama it is quick-fried factor it is very much, but the quality of enamelled pressed steel in itself can produce it is very big Influence.In order to improve the fish scaling resistance of steel plate, the quality for improving steel plate interior tissue and raising steel plate is very important.Will Prevent that squama is quick-fried, enough field trashes, hole or precipitate must be contained in steel.Field trash is conducive to improve fish scaling resistance, Reason is around field trash that there are tiny holes these tiny holes play a part of catching hydrogen, become hydrogen trap.But Field trash can damage the field trash of the forming property and mechanical property of steel plate, different types of field trash and different Size Distributions Influence be also not quite similar, therefore, to be allowed a choice for the characteristic of field trash.
In view of the above-mentioned problems, applicant carries out a series of researchs so as to develop a variety of new steel grades, however, steel grade can not Directly apply in actual product, but needs further impose enamel on its surface and could use in practice.Different In enamel product, have nothing in common with each other to the performance emphasis of glassed steel, as glassed steel includes high temperature resistant enamel, insulating enamel, resistance to Grind the kinds such as enamel.The application makes plate possess resistance to elevated temperatures, so as to solve by spraying high temperature resistant enamel in plate surface The problem of prior art glassed steel resistance to elevated temperatures is insufficient, obtained product can be widely used for combustion turbine system, aircraft heat is handed over The high-temperature fields such as changing device, airplane heat exchanger, turbine assembly.
The content of the invention
The application provides the good hot rolled plate of a kind of intensity height, enamel coating strong adhesive force, fish scaling resistance and preparation side Method, plate surface enamel and preparation method.
This application provides a kind of counterenamel steel hot-rolled sheet material, it is characterised in that the plate chemical composition is to press Percentage by weight, C:0.02-0.05%, N:0.012-0.015%, S:0.01-0.05%, P:≤ 0.05%, Si:≤ 0.04%, W≤ 0.025%, Mn:0.05-1.5%, Al:0.01-0.05%, Ti:0.01-0.025%, surplus are Fe and inevitable impurity.
Pass through the accurate control to W content in plate, and making between its content and remaining element in process of production Relation can obtain the optimal performance of plate, and wherein relational expression can be shown with following formula:W=(C+0.98N+0.5S)/2-Ti.And due to The measurement of each element content is inevitably present error in actual production process, therefore the error range of above formula is controlled ± 1% Within be allowed, those skilled in the art can be appreciated that reasonability existing for error.And for the theoretical angle of above-mentioned arithmetic expression For degree, it can speculate that the ratio between element W and each element can reach its gap as the site of trapping hydrogen, so that Make it have height and catch the state of Hydrogen Energy power, so as to be easy to react and absorbed with hydrogen.Scheme listed by above formula is this Shen Please hot rolled steel plate most preferred technique scheme.
