Problems solved by technology

Dry powder fireclay is used after manual mixing with water before use, often resulting in leaky joints due to uneven mixing
Wet fire clay is made by the manufacturer and sent directly to the steel mill for use. However, this kind of wet fire clay generally has problems such as short storage time, easy drying, poor adhesion (easy to fall off) and easy deterioration, which seriously affects the site. Construction and cause a lot of waste of resources
[0003] In addition, due to the rise in raw material prices and the continuous reduction in sales prices, the profit margin of this product has been continuously compressed, and the production pressure of enterprises is increasing.

Embodiment 1

[0015] A kind of aluminum chrome joint cement, it is made up of following components by weight:

[0016]

[0017] The reclaimed magnesia-chrome bricks are prepared according to the following method: select recycled or discarded magnesia-chrome bricks, cut off their erosion layer and metamorphic layer, put them in a drying kiln and dry them at 250°C for 48 hours, and then crush them to obtain a particle size of ≤0.074 mm powder. The produced magnesia-chrome brick regenerated materials must meet the requirements in the table below.

[0018] Table 1 Physical and chemical index requirements for recycled magnesia-chrome bricks

Abstract

The invention discloses an aluminum-chromium seaming mortar. The aluminum-chromium seaming mortar comprises the following components by weight: 30 to 85 parts of a magnesium-chromium brick reworked material with a particle size of no more than 0.074 mm, 5 to 45 parts of alumina micro powder with a particle size of no more than 20 mu m, 2 to 10 parts of silicon micro powder with a particle size of no more than 1.5 mu m, 1 to 5 parts of sodium carboxymethylcellulose, 3 to 10 parts of clay powder with a particle size of no more than 0.088 mm and 10 to 20 parts of water. The invention further discloses a preparation method for the aluminum-chromium seaming mortar. Compared with the prior art, the seaming mortar provided by the invention has the advantages of long storage time, good adhesion, good anti-erosion performance, uneasy inclusion of steel, low production cost, etc.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to an aluminum-chrome joint mortar and a preparation method thereof. Background technique [0002] Refractory cement is often used to fill the gaps when installing refractory materials such as slide plates, upper and lower nozzles, seat bricks, slag retaining walls and slag retaining dams. At present, dry powder fireclay or wet cement is mainly used for caulking. Dry powder fireclay is used after manual mixing with water before use, often resulting in leaky joints due to uneven mixing. Wet fire clay is made by the manufacturer and sent directly to the steel mill for use. However, this kind of wet fire clay generally has problems such as short storage time, easy drying, poor adhesion (easy to fall off) and easy deterioration, which seriously affects the site. Construction and cause a lot of waste of resources. [0003] In addition, due to the rise in raw material pr...
