Embodiment 1

[0020] A corundum wear-resistant and refractory plastic, which is composed of the following raw materials in mass percentage:

[0021] Corundum: 70.48%; Chrome corundum: 15%; Zircon: 8%; Alumina fine powder: 2%; Zirconium powder: 0.5%; Lanthanum and lanthanide metal oxide fine powder: 0.01%; Agent: 2%; Binder: 2%. The production steps are as follows:

[0022] (1) Fine grinding: send the corundum, chrome corundum and zircon into the pulverizer and fine grinder respectively, and pulverize until the particle diameter is less than 1mm;

[0023] (2) Premixing: send the finely ground corundum, chrome corundum and zircon and alumina micropowder in step (1) into a sand mixer in proportion to premix for 8 minutes;

[0024] (3) Mixing: add the dispersant to the premixed raw materials in step (2), mix in the sand mixer for 20 minutes; add zirconium powder, lanthanum and lanthanide metal oxide micropowder and yttrium powder, Mix within 20 minutes; add binder and mix for 20 minutes to m...

Embodiment 2

[0028] A corundum wear-resistant and refractory plastic, which is composed of the following raw materials in mass percentage:

[0029] Corundum: 70.4%; Chrome corundum: 15%; Zircon: 8%; Alumina fine powder: 2%; Zirconium powder: 0.5%; Lanthanum and lanthanide metal oxide fine powder: 0.05%; Agent: 2%; Binder: 2%.

[0030] The production steps are substantially the same as in Example 1. After completion, 10 samples were randomly sampled for high-temperature performance test, and the results are shown in Table 1.

Embodiment 3

Abstract

The invention provides a corundum wearing-resistant plastic refractory. The corundum wearing-resistant plastic refractory comprises corundum, chromium corundum, zirconite, alumina micro powder, zirconium powder, lanthanum and lanthanum group metal oxide micro powder, and 0.01-0.1% of yttrium powder. The invention further claims a preparation method of the corundum wearing-resistant plastic refractory at the same time. The preparation method comprises the steps of fine milling, pre-mixing, mixing, drying, sorting, checking, packaging and storing. Through adding zirconium powder, lanthanum and lanthanum group metal oxide micro powder, and yttrium powder, the high-temperature bonding property of the plastic is improved, and therefore the slag resistance, the thermal stability and the service life of the product are improved.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a corundum wear-resistant refractory plastic and a preparation method thereof. Background technique [0002] Refractories refer to a class of inorganic non-metallic materials with a refractoriness not lower than 1580°C. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, and are used in the largest amount in the metallurgical industry, accounting for 50% to 60% of the total output. Various heating furnaces, soaking furnaces, annealing furnaces, sintering furnaces, and electric furnace roof linings in the iron and steel industry cannot use general shaped refractory materials, only special refractory plastics can be used, and refractory plastics are made of refractory aggregates. It is a kind of refractory material that can be constructed by ramming method after being m...
