Process for preparing foamed glass form titan-containing blast furnace slag

The invention provides a method for preparing foam glass by utilization of titaniferous blast furnace slag, belonging to the metallurgical resource comprehensive utilization and material preparation field. The method mainly is to take the blast furnace slag containing 14 to 29 percent of TiO2 as base material, to adequately introduce silicious raw materials to generate vitreous substances, to add foaming agent, foam stabilizer and fluxing agent, and to prepare the foam glass with a specified heat treatment system. The method solves the problems that the prior titaniferous blast furnace slag is difficult to utilize and process and the utilization rate of the titaniferous blast furnace slag in the material preparation field is low, not only creates a novel path for utilization of the titaniferous blast furnace slag but also finds very cheap raw materials for production, and has the advantages of low production cost, good product quality, simple production operation, no secondary pollution and so on.
