Manufacturing method of novel rock wool material based on iron ore

Abstract

The invention discloses a manufacturing method of a novel rock wool material. The method comprises the following steps: preparing a mixed raw material from the following components in parts by weight: 25-35 parts of ferro-titanium stone, 35-45 parts of basalt, 5-8 parts of limestone, 8-10 parts of slag, 20-30 parts of coke and 3-5 parts of an auxiliary material; putting the mixed raw material into a cupola furnace to obtain magma; then performing fiber forming, collecting cotton, laying cotton and pressing on a three-dimensional cotton presser; and curing and trimming to obtain the novel rock wool material. The prepared rock wool material is black in appearance and good in fiber forming and hydrophobic effects, and has good mechanical properties.

Description

Technical field [0001] The invention relates to the field of new rock wool materials, in particular to a method for manufacturing a new rock wool material based on iron ore. Background technique [0002] Rock wool is an inorganic material, a fiber aggregate made from natural mineral rocks. The general rock wool on the market is made on the basis of basalt, and the appearance ranges from light yellow or yellow to brown. [0003] The existing rock wool manufacturing process involves the fibers formed by blowing the magma into which the ore feed is melted, and forming a loose multilayer rock wool layer by pendulum laying. This multilayer rock wool passes through the upper and lower rollers of the cotton press After being compacted, it enters the curing furnace to solidify to form rock wool products. The ordinary rock wool made by this process has only two-dimensional stacking in the thickness direction, without cross-linking, so the peel strength is very low. When used as a building...

Utility model patent CN201220326750 discloses a rock wool setting system with wrinkling function, but it does not disclose details of how to achieve wrinkling

Chinese patent application 201010512495.8 discloses a rock wool pleating machine, which realizes the pleating of rock wool through the speed difference of multiple sets of upper and lower pressure rollers. The products obtained by this pleating method make each rock wool layer wrinkle. Wrinkles produce component force in the thickness direction, which is beneficial to improve the peel strength of rock wool products, but according to the product principle, it can not establish a connection between layers, so the effect on improving the peel strength is limited, and the actual sales in the market The product also confirms this

Another disadvantage is that the undulating folds in the rock wool product actually increase the tensile allowance of the rock wool layer in the longitudinal direction, giving the rock wool product more elasticity in the longitudinal and thickness directions. , this property is often not desirable
