Embodiment 1

[0021] Environmentally friendly siliceous dry material, including the following components and the mass percentage of each component is: quartz sand with a particle size of 3mm: 14wt%; quartz sand with a particle size of 0.3 to 3mm (including 0.3mm, excluding 3mm): 64.3wt%; quartz sand with a particle size of 0.088mm: 16wt%; anhydrous glucose: 5.0wt%; borax: 0.7wt.%. This formula is the best formula, considering performance and cost. The proportion of quartz sand is strictly controlled according to different particle sizes, which improves the product quality. The additive used is anhydrodextrose, which is an organic compound, ie glucose without water of crystallization. It is colorless crystal or white crystalline powder; odorless and sweet. Dextrose anhydrous is a nutraceutical. It can be used to make glucose injection, glucose sodium chloride injection, compound sodium lactate glucose injection and other medicines. Baking and heating completely solves the harm of toxic and...

Abstract

The invention discloses an environment-friendly silicon dry-type material and a preparation method thereof. The environment-friendly silicon dry-type material comprises the following components in percentage by mass: 13.6-14.4 wt% of quartz sand with the particle size of 3mm, 63.3-65.3 wt% of quartz sand with the particle size of 0.1-3mm, 15.5-16.5 wt% of quartz sand with the particle size of 0.088mm, 4.7-5.3 wt% of anhydrous glucose and 0.6-0.8 wt.% of sodium borate. When the silicon dry-type material is used for smelting plain steel, the utilization ratio can reach 90% or above, thereby greatly saving the consumption of mineral resources. Since the quartz sand is low in price, the cost is only one twentieth of the magnesium dry-type material, thereby greatly lowering the steelmaking cost in the aspect of raw materials. On the premise of lowering the cost, the environment-friendly silicon dry-type material can completely satisfy the smelting requirements for plain steel without lowering the product quality. The anhydrous glucose used as the additive is odorless, tastes sweet, and can not generate any toxic or harmful gas during baking heating, thereby protecting the environment and good health of workers.

Description

【Technical field】 [0001] The invention relates to the field of metallurgy, in particular to the improvement of an environment-friendly siliceous dry material and a preparation method thereof. 【Background technique】 [0002] At present, the dry materials for the production of ordinary steel grades and superior steel grades all use magnesia or forsterite as the main raw material component, and use solid phenolic resin as the binder. The general service life of this kind of magnesium dry materials is 24-45 hours, while the production of ordinary steel generally only needs 8 to 12 hours, the utilization rate is less than half, a waste of mineral resources, and the cost of steelmaking is very high. [0003] Traditional dry materials generally use powdered phenolic resin as a binder. The adhesive contains a certain amount of formaldehyde and free phenol, which will produce very smelly and harmful fumes during baking and use, endangering the environment and the health of employees...
