Embodiment 1

[0025] This implementation is aimed at the method of producing mineral wool by using quenched and tempered ferronickel smelting waste residue in a 1t electric arc furnace. Ferronickel smelting waste slag 200kg, borax 10kg, the ratio between borax and waste slag is 0.05; borax and waste slag are mixed evenly and then added to the electric furnace, and the arc is raised to heat up. After 50 minutes, the raw materials are completely melted, and the temperature is measured. After the temperature reaches 1600°C, The electric furnace is turned on to keep warm power. Take 500 g of molten slag, and measure the viscosity value of molten slag in the temperature range of 1600°C-1500°C in a viscometer. After the temperature-viscosity value is suitable, the temperature measured slag is 1593°C; the slag is discharged from the furnace, and the slag is dumped on the rollers of the four-roller centrifuge through the diversion groove, and the four-roller speeds are respectively 1#2070r / min, 2#3...

Abstract

The invention relates to application of a boron-osxygen-containing compound to production of mineral wool and belongs to the technical field of production and manufacturing of the mineral wool. According to the application of the boron-oxygen-containing compound to the production of the mineral wool, provided by the invention, smelting slag is used as a raw material and the boron-oxygen-containingcompound is taken as a process control agent; the process control agent is added into the smelting slag and is heated to be fused; a fused melt is prepared into the mineral wool; when the process control agent is used, a temperature spanning range is 65 to 100 DEG C when a viscosity range of the melt is 1 to 3Pa.s. According to the application provided by the invention, reasonable proportioning between borax and ferro-nickel smelting waste slag is ingeniously utilized, and physical and chemical properties of the ferro-nickel smelting waste slag are remarkably improved, so that the ferro-nickel smelting waste slag is changed into a high-quality raw material and the problem that ferro-nickel waste slag is not suitable for producing the mineral wool is solved; a produced product can be widely applied to the fields of buildings and the like, and recycling and economic application of the waste dreg is realized.

Description

technical field [0001] The invention relates to the application of a boron-oxygen compound in the production of mineral wool, belonging to the technical field of mineral wool production and manufacture. Background technique [0002] Mineral wool is an inorganic silicate fiber material, which has the advantages of heat insulation and heat preservation, and is widely used in the construction field. There are two main raw materials for the production of mineral wool, one is rock, and the other is metallurgical waste residue. The mineral wool produced from rock raw materials is called rock wool, and the mineral wool produced from metallurgical waste residue is called slag wool. At the same time, nickel is an essential element for the production of stainless steel. With the development of my country's iron and steel industry, a large amount of nickel-iron alloy waste has been piled up, and the pile of metallurgical solid waste has brought enormous pressure to the environment. Th...
