Problems solved by technology

[0003] Due to the advancement of titanium slag smelting technology and the problem of unloading of the slag pot or slag tank, the titanium slag has not been cooled to 200°C before the slag is hung. Still in close contact, the titanium slag cannot effectively fall off from the slag pot or slag tank, which affects the demoulding time of titanium slag, prolongs the follow-up process time of titanium slag, and hinders the reduction of titanium slag production cost
[0004] With the enlargement of existing titanium slag equipment and the expansion of output, the existing titanium slag cooling method often starts to hang slag after 4 hours, and at this time, there are still a large amount of red slag or even liquid red slag after the titanium slag is broken, which is dangerous. Very high, and red slag is easy to oxidize, reducing the quality of titanium slag

Embodiment 1

[0036] Weigh 23Kg of dust removal ash, 3Kg of magnesia refractory material, 2Kg of site ash, and 2Kg of lime, mix them into the mixer and stir for 10 minutes, then add 60Kg of titanium slag to cool the wastewater, mix evenly to obtain slurry, and brush the slurry on the inner wall of the slag basin with a brush 2 layers, brush 4 layers on the bottom, after half an hour, the slurry on the surface of the slag pot can be connected to the slag pot to pick up the slag. After the slag was cooled by spraying water in the slag basin for 6 hours, the slag was turned over. After turning over the slag, a small amount of titanium slag remained at the bottom of the slag basin, and the average demoulding efficiency of the titanium slag was about 96.25%.

Embodiment 2

[0038] Weigh 25Kg of dust removal ash, 2Kg of magnesia refractory material, 1.5Kg of site ash, and 1.5Kg of lime, mix them into the mixer and stir for 12 minutes, then add 60Kg of titanium slag to cool the waste water and mix evenly to obtain a slurry, which is brushed on the inner wall of the slag basin Brush 2 layers, and brush 4 layers on the bottom. After half an hour, the slurry on the surface of the slag pot can be connected to the slag pot to pick up the slag. After the furnace slag was cooled by spraying water in the slag basin for 6 hours, the slag was turned over. After turning over the slag, a small amount of titanium slag remained at the bottom of the slag basin, and the average demoulding efficiency of the titanium slag was about 95.48%.

Embodiment 3

[0040] Weigh 24Kg of dedusting ash, 4Kg of magnesia refractory material, 1Kg of site ash, and 1Kg of lime, mix them into the mixer and stir for 15 minutes, and then add 60Kg of titanium slag to cool the waste water and mix evenly to obtain a slurry. Use a brush to brush the slurry on the inner wall of the slag basin for 2 After half an hour, the slurry on the surface of the slag basin is dry, and then the slag basin can be used to pick up the slag. After the slag was cooled by spraying water in the slag basin for 6 hours, the slag was turned over. After turning over the slag, a small amount of titanium slag did not fall off at the bottom of the slag basin, and the average demoulding efficiency of the titanium slag was about 97.23%.

[0041]From the analysis of the above-mentioned Examples 1 to 3, it can be seen that the raw materials of the titanium slag release agent of the present invention are all recycled secondary resources, which are cheap and easy to obtain, which greatl...

Abstract

The invention belongs to the technical field of titanium slag smelting, and particularly relates to a titanium slag release agent and a utilization method thereof, and provides the titanium slag release agent which is low in price, high in demolding efficiency, easy to prepare and easy to store. The titanium slag release agent comprises the following components by weight percent: 70% to 90% of dedusting ash, 5% to 15% of a magnesia refractory material, 2% to 10% of field ash, 2% to 10% of lime, and unavoidable impurities. The utilization method comprises the steps of adding the titanium slag release agent into titanium slag cooling wastewater, carrying out uniform mixing to obtain slurry, smearing the slurry onto the inner wall and the bottom of a slag basin, and waiting the slurry to dry. According to the titanium slag release agent, the raw materials are secondary resources, can be recycled, and are low in price and easy to obtain, the demolding performance of the release agent is remarkably improved, demolding efficiency can reach 95% or above, and a high-efficiency and economic new thought is provided for titanium slag demolding.

Description

technical field [0001] The invention belongs to the technical field of titanium slag smelting, and in particular relates to a titanium slag release agent and a using method thereof. Background technique [0002] At present, the titanium slag released from the furnace at home and abroad is cooled by spraying water with slag basin or slag tank, and the titanium slag is cooled to about 200 °C, and then the titanium slag is demoulded from the slag basin or slag tank, and the titanium slag after demoulding is sprayed again. The finished titanium slag is obtained after water cooling to below 100°C, coarse crushing and fine crushing, measurement and packaging. [0003] Due to the advancement of titanium slag smelting technology and the problem of unloading of the slag pot or slag tank, the titanium slag has not been cooled to 200°C before the slag is hung. Still in close contact, the titanium slag cannot effectively fall off from the slag basin or slag tank, which affects the demo...
