Continuous Type Heat Treatment Furnace For Oil Cooler / Laminated Evaporator Brazing

Strong Heating Ability , Continuous Brazing Furnace , Electric Heating Alumium

Overview

It is a controlled atmosphere aluminum brazing furnace system. It is mainly used for continous brazing the workpieces of aluminum water tank, oil cooler, medium cooler, warm air, pipe-belt-type condenser, evaporater, parallel-flow condenser,laminated evaporator, power plant air cooler under the protection of nitrogen.

Hard brazing

Brazing solder has a melting point of more than 450°C and high joint strength,The strength of hard brazing joints is high, some kinds of brazing solders can be used in high temperature. There are many kinds of solder for hard brazing, the most widely used solder based on aluminum, silver, copper, manganese and nickel. Aluminum base solder is often used for brazing aluminum products.Silver base copper filler metal is often used for brazing copper and iron parts.

How to decide the heating speed?

On the premise of uniform heating, therefore, should try to shorten the heating time which improve the heating speed. When determine the specific heating speed, it must be decided by the weldment size, base metal and the features of the solder.

Features

• Fine and reasonable heating furnace section, hardware selection and software parameter adjustment of high-precision advanced temperature control instrument, make furnace temperature control accuracy ≤± 0.2 °C, the product temperture difference in the brazing zone is ≤3°C;

• Strong heating ability of the dry oven and the quick circulating wind inside the furnace ensure that the workpieces inside the furnace have no moisture to damage the workpiece quality;

• The advanced and completed control system makes the production line integrated and intelligent.

Technical characteristics of aluminum brazing furnace

Process flow of aluminum brazing:Put on the parts - degreasing (heat degreasing or water cleaning degreasing)- brazing spray - drying - preheating - brazing - cooling (under protective atmosphere)- strong cooling – take down the parts

The atmosphere in the brazing furnace is significant during the brazing process, it requires that the Oxygen concentration should be below 10 ppm and the drew point is lower than -72°C. The temperature uniformity of the same product is especially important when the brazing temperature is reached, the general requirement is ±3℃. The requirements for some products are even higher

Our company insists on superior quality, strict manufacturing processes, enthusiastic service attitude and reasonable price to return customers . We hope that our customers could put forward valuable opinions, give counsel, engaged in innovation and development of our industrial furnace in order to push the progress of the industrial science and technology.
