Embodiment Construction

[0006] The production method of the agglomerating adhesive for smelting metal of the present invention is: first add 50~60 tons of water in the batching tank, after heating to 30~70 DEG C, then add dry powdery magnesium lignosulfonate while stirring ( or sodium lignosulfonate) 23-33 tons, then add 0.5-1.5 tons of urea, 0.3-3.0 tons of hexamethylenetetramine, 4-7 tons of starch, 0.1-1.0 tons of phenol, and 0.1-1.0 tons of formaldehyde, and stir evenly Then use sulfuric acid to adjust the pH value of the mixture to neutral, then heat the temperature in the batching tank to 30-70°C, stir fully to make it work for 1-3 hours, then stop heating and let the mixture stand still It can be used after three days.

[0007] Precautions in the production process: 1. Wear labor protection articles during the operation; 2. Be careful when adding hexamethylenetetramine to prevent the medicine from splashing on the skin; 3. The operator should stand at the The upper air outlet prevents the med...

Abstract

The invention discloses a briquetting agglomeration adhesive for smelting metal. The preparing method of the adhesive comprises: a certain amount of water is added into a dosing tank and stirred after being heated, and simultaneously dry powered wooden magnesium spar sulfonate (or wooden sodium sulfonate) are added to the water, then the water is added with urea, hexamethylene tetramine, starches, phenol and formaldehyde, the PH value of the mixture is adjusted to be neutral by using sulphuric acid after being evenly stirred, then the temperature in the dosing tank is heated to be 30 to 70 DEG C, heating can be stopped after 1 to 3 hours of action by fully stirring, and the mixture can be used after being stood for three days. The adhesive has wide source, is simple in production process, low in product cost, and good in cohesive effect, does not produce waste materials and is good for environmental protection, so the adhesive is a rather good material of briquetting agglomeration for smelting metal.

Description

1. Technical field [0001] The invention relates to an adhesive for metal smelting, in particular to an agglomerating adhesive for metal smelting. 2. Background technology [0002] In the process of metal smelting, after mixing metal-containing ore, washed coal, binder and mixture, after rod milling, rolling, compacting, making agglomerates and making agglomerates, qualified green agglomerates are made. The raw agglomerate ore is put into the furnace and undergoes high-temperature smelting to obtain the required metals. Before the present invention was proposed, the binder used for agglomeration was pulp binder. This kind of adhesive can only be obtained from the papermaking process, the source of materials is narrow, and the cost is high. The dry powder pulp adhesive treated by environmental protection has poor bonding effect after adding water. 3. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the purpose of the present invention...
