Prefabricated refractory wallboard used for graphitized furnace and manufacture method thereof

Abstract

The invention discloses a prefabricated refractory wallboard used for a graphitized furnace. The prefabricated refractory wallboard comprises a wallboard body provided with a steel reinforcement framework structure, wherein the wallboard body is provided with a lifting ring and a plurality of air vents run through horizontally. The manufacture method for the prefabricated refractory wallboard comprises the steps of 1) taking flint clay as the main material and the aluminate cement, clay fine powder, a-Al203 micro powder, SiO2 micro powder, explosion-proof fibers and the like as the auxiliary material; 2) manufacturing the steel reinforcement framework; 3) conducting proportioning on the flint clay according to the three-level grading, then adding the aluminate cement, the a-Al203 micro powder, the SiO2 micro powder, the clay fine powder, the explosion-proof fiber and other auxiliary materials, and then adding water and stirring after premixing, finally adding the materials into a mould for vibration moulding; and 4) routine maintenance. The prefabricated refractory wallboard disclosed by the invention is simple in structure, convenient in manufacturing, low in labour intensity of the worker and short in maintenance cycle, saves the burning process, improves the capacity of the graphitized furnace, and has the characteristics of energy conservation, environmental friendliness and high efficiency, and the wallboard can be ensured for 50 times.

Description

technical field [0001] The invention relates to a refractory masonry component for a graphitization furnace and a manufacturing method thereof. Background technique [0002] The graphitization furnace is the key equipment of the carbon plant. The furnace body must withstand long-term high-temperature work and frequent cooling and heating processes during use. In order to prolong its service life, the refractory materials used are required to have good thermal shock stability. At present, the furnace wall of the graphitization furnace body in my country is usually built with refractory standard bricks with a size of 230×114×65. When each furnace is fired and shut down, the furnace wall needs to be removed for cleaning and maintenance, and the next furnace needs to be rebuilt. Building the furnace wall requires high labor intensity, low production efficiency and high production cost. Contents of the invention [0003] The problem to be solved by the present invention is to p...
