Rock Wool Cold Slag Electric Furnace Rock Wool Electric Furnace

Product Specification

Process description:

The main raw materials of rock wool electric furnace basalt ore and auxiliary materials, the prepared raw materials after drying system, through the feeding system into the high bunker of electric furnace storage. After measuring and weighing the raw materials through the distributing system, the raw materials are lowered into the furnace by the feeding pipe in the furnace, and the thin materials are continuously heated by electric power for submerged arc smelting. After melting to meet the temperature requirements, the thin materials are released through the slag outlet and enter the centrifuge to make rock wool products. 

The flue gas of the electric furnace is cooled by the smoke pipe into the high-temperature cloth bag dust collector for treatment, and discharged after reaching the smelting emission standard.  

Production of rock wool electric furnace equipment advantages:

(1) equipment operation flexibility, slag flow controllable, simple operation;

(2) Adopt advanced impedance control method and introduce high temperature feedback;

(3) high degree of automation, centralized control of the whole smelting process;

(4) Fast melting speed, can contact feeding, continuous discharge;

(5) smelting melting process without coke;

(6) The equipment performance is stable and can work continuously for 24 hours;

(7) Production waste can be recycled, resulting in less waste;

(8) The flue gas is easy to recover and the emission is small.

Rock Wool Cold - Slag Electric Furnace

1. Core Characteristics
   • High solid waste utilization rate: It can take blast furnace slag, iron tailings and other industrial cold slags as the main raw materials, with the proportion of solid waste in raw materials up to more than 70% after proportioning. It turns waste into treasure, reduces the consumption of natural mineral resources such as basalt, and conforms to the concept of circular economy.
   • Strong material adaptability: It can handle cold slag raw materials in the form of particles or powder. It doesn't require large pieces of raw materials. The raw materials are easy to obtain and low in cost. It can also adjust the proportion of auxiliary materials such as silica sand and bauxite to flexibly control the acidity coefficient of the melt and meet the quality requirements of rock wool.
   • Energy-saving and environment-friendly operation: It uses electric energy as the heat source, without burning fossil fuels. Thus, it avoids the emission of sulfur dioxide, nitrogen oxides and other harmful gases. The amount of flue gas produced is small, and the waste gas treatment system is relatively simple. Some equipment can also recover the waste heat in the production process to further reduce energy consumption.
   • Stable melting effect: Equipped with an intelligent temperature control system, it can stably heat the raw materials to above 1500℃. It ensures that the temperature and viscosity of the molten body meet the requirements of the subsequent centrifugal fiber forming process, and reduces the fluctuation of rock wool product quality.

Rock Wool Electric Furnace

1. Core Characteristics
   • Diversified heating forms: The common heating method is electric arc heating. Some large - scale equipment adopts arc resistance furnace structure. It is equipped with three electrodes to heat raw materials to 1600 - 2000℃. It can fully melt and homogenize raw materials, including natural minerals and industrial waste.
   • Flexible and stable operation: It supports continuous feeding and continuous slag tapping. It can be matched with the automatic distribution system of raw materials and the centrifugal fiber forming system. The flow and temperature of the melt are easy to control, and the operation is simple. It can adapt to the production needs of different scales of rock wool products such as rock wool boards, pipes and blankets.
   • Durable structure design: The furnace body adopts high - alumina refractory materials or refractory castables. The smoke hood is usually designed with a water - cooled structure. The key parts such as electrodes are fixed and protected by copper tiles and disc springs. It can resist high temperature corrosion and thermal shock, and the service life of the equipment is long.
   • Strong scalability: The equipment capacity can be customized according to production needs. For example, the installed capacity of small and medium - sized equipment is about 2500 - 3200 KVA, and the melting capacity of large - scale equipment can reach 10 - 30 tons/hour, with a melt storage capacity of 100 - 300 tons.
