Product Description

Product Description

 

^{PRE-CAST OVEN DOORFOR COKE OVEN}

^{INTRODUCTION
The surface of pre-cast refractory door is made of composite ceramic
material.Pre-cast refractory is shaped by high frequency vibration.
The material has low porosity,high density and good uniformity.There
is crystalline ceramic refractory adhere to the pre-cast surface,which
have high strength,good abrasion resistance and corrosion resistance.
It has been reduced the physical damage during the operation and tar
and other chemicals erosion to the refractory.
FEATURE
1.Simple structure and easy to install
2.Good integrity and impermeabiity
3.The working life of the door is longer than the traditional one.
4.The pre-cast refractory door has the performance of energy-saving
and environment-friendly,which can help the factory to reduce the
cost and improve the overall working efficiency.}

   

ZERO THERMAL EXPANSION SILICA BRICK FOR COKE OVEN

INTRODUCTION

Zero thermal expansion silica brick is also known as fused-quartz brick or thermal shock resistance silica brick.
It has extremely low thermal expansion rate,excellent thermal shock resistance,high SiO2 content etc.Zero thermal expansion silica brick is widely used in hot repair project on coke oven.
By using zero thermal expansion silica brick,the maintenance time for coke oven shortens greatly.
Cunse has the ability on providing the hot repair solution on coke oven,we also can do the EPC project on regular maintenance of coke oven.

 

NEW CERAMIC AIR DISTRIBUTION
 

INTRODUCTION

The new ceramic air distribution is suitable for the air distribution hole of the heat recovery coke oven,and can also be used as the door material of the horizontal coke oven.This material has excellent resistance to rapid cooling and rapid heating and chemical stability,which can significantly improve production Efficiency,reduced maintenance cost and frequency.

 

NEW  CERAMIC CHUTE
 

INTRODUCTION

The new ceramic chute is suitable for the grooves and other parts where the high-temperature solution flows through.The surface is coated with a new high-performance microcrystalline glaze layer,which  has  the  characteristics  of anti-flaking,wear-resistant,anti-erosion  and  non-sticking  materials,which  can  significantly improve production efficiency and reduce maintenance cost and frequency,avoid  solution  contamination.

 

ASCENDING  PIPE PRE-CAST REFRACTORY FOR COKE OVEN

INTRODUCTION

The upper area of ascending pipe is used casting method by monolithics and the lower area is made of high temperature glazed refractory.By using the innovating technology,our ascending pipe is an ideal choice to avoid the gather of the coke and carbon with excellent heat preservation.
