KKQ Perlite Expansion & Vitrification Furnace is invented by our factory director and senior engineer Kong Keqiang in February，2003, in the same year, He obtained patent for this kind of furnace, and it is the first one in the world to be put into industrial production, there are 30 furnaces which have already running for 5 years continually ,they are used to produce closed perlite vitrified microspheres and hollow perlite vitrified microspheres .We use 6 microcomputers to full automatically control technology processes of closed pearlite vitrified microspheres such as sand softening, crystal water vapourization instantaneously, size of hollow balling 、shell vitrified for water-proof and shell hardening. In the past five years in China , 80% of perlite vitrified microspheres used for wall heat insulation mortar were produced by our factory’ Perlite Expansion & Vitrification Furnace. At present, many countries in the world such as America, Canada, Australasia, Poland, Thailand, Russia and South Korea have gradually adopted our furnaces to produce new wall heat preservation materials------ perlite vitrified microspheres(KKQ Microsphere).

Ever since the first Closed-pore Perlite Expansion & Vitrification Furnace was invented , we have successively created the second and third generation ones. Especially KKQ Perlite Expansion & Vitrification Furnace（Ⅲ）we designed out in 2009, we have achieved a revolutionary breakthrough in its many performance such as energy-saving, heat insulating, vitrification rate, productivity and fault rate. It went into production successfully in Changda Heat Insulating Material Company in Xinyang, its output reaches up to 30 tons per day, which shocked domestic heat-insulating mortar industry, compared with the 20 sets of furnaces we sold to Xinyang company three years ago, output of the Perlite Expansion & Vitrification Furnace (Ⅲ) is increased one times, power consumption is about 300kwh per hour, and its volume-weight is smaller, all of which make Perlite Expansion & Vitrification Furnace (Ⅲ) the first choice of many large enterprises.


KKQ Microsphere is new heat insulating material which is glassy--shell and hollow and produced by KKQ Expansion & Vitrification Furnace, its performance and usage is superior to ordinary expanded perlite. In one word, it is a breakthrough of perlite heat insulating material and at the same time a great invention of new material in this century. The mark “KKQ” is abbreviation for name of patentee Kong Keqiang .

Wuhan Hankou Furnace CO., LTD is a large famous company which possesses 40 years’s furnace manufacturing experience. It produces nearly one thousand sets of industrial furnaces and kilns annually. What’s more ,it has obtained many national patents and ranks forefront internationally in furnace industries .
