Steam Heating Rubber Products Vulcanizing Tank Autoclave Machine

A rubber autoclave, also known as a rubber curing autoclave or rubber vulcanizing autoclave, is a specialized piece of equipment used in the rubber industry for the curing or vulcanization of rubber products.

Now this page, it's steam heating autoclave machine, which uses steam as heating medium. User can use the steam generated by a steam generator, or we can make the machine with electricity heating bar, the user input water into the tank, the steam can be generated by heating the water through the heating bars.

It is essentially a high-pressure and high-temperature vessel that provides an environment for the rubber material to undergo the vulcanization process.

The rubber autoclave is typically a cylindrical or spherical chamber made of robust materials such as steel. It is designed to withstand high pressures and temperatures. The rubber products to be cured are placed inside the autoclave along with any necessary curing agents or accelerators.

Once the rubber material is loaded, the autoclave is sealed, and steam or other heating media is introduced into the chamber. The temperature and pressure are carefully regulated and maintained at specific levels required for

the vulcanization process. The combination of heat, pressure, and time allows the curing agents in the rubber compound to react, leading to the cross-linking of the polymer chains and the transformation of the raw rubber into

a stronger, more resilient material.

Rubber autoclaves are commonly used in the production of various rubber products, including tires, rubber hoses, conveyor belts, and gaskets. They offer advantages such as uniform curing, excellent control over temperature

and pressure, and the ability to process large quantities of rubber products simultaneously.

The control system of a rubber autoclave enables operators to set and monitor the temperature, pressure, and curing time to achieve optimal vulcanization conditions. This ensures consistent and reliable curing results, resulting

in high-quality rubber products with desired physical and mechanical properties.

Control Panel

we design different type control panel according to machine needs or customers' requirements, here just put one for a reference.

Control Box

CHNT brand, it's best brand of China made, works accurate and stable. When customers have different power voltage supply, we put a transformer into the control box, as you can see it from below picture.

Tank body, we use Q345R as raw material

Steel Q345-R, as a widely used low alloy high-strength structural steel, represents the yield strength with "Q" in its grade, while "345" indicates that the yield strength (in megapascals, MPa) of this steel under

standard test conditions reaches 345MPa. The subsequent "R" symbol specifically indicates that the steel is suitable for container manufacturing,

that is, it has good welding performance and certain high-temperature resistance characteristics, and is suitable for the production of pressure vessels, storage tanks and other equipment.

The characteristics of Q345-R steel include:

1. Mechanical properties: In addition to having a yield strength of no less than 345MPa, it also has good tensile strength, generally up to 470-630MPa, as well as good toughness, plasticity, and weldability, ensuring

the safety of components under complex stress states.

2. Chemical composition: As a low alloy steel, Q345-R contains small amounts of alloying elements such as manganese (Mn), silicon (Si), titanium (Ti), niobium (Nb), etc. The addition of these elements can significantly

improve the comprehensive mechanical properties of the steel without significantly increasing its weight, ensuring strength while reducing the structural weight.

3. Corrosion resistance and high temperature resistance: Although Q345 series steel is mainly designed for room temperature environments, Q345-R has certain corrosion resistance and resistance to medium and

low temperatures (usually from room temperature to about 400 ℃) through specific composition adjustments and heat treatment, making it suitable for manufacturing containers that can withstand certain temperature and pressure.

4. Processing performance: Good cold forming and welding performance make Q345-R easy to process into various complex shaped components, meeting different engineering needs, especially in the fields of chemical, petroleum,

energy, etc. It has a wide range of applications.

In practical applications, Q345-R steel needs to undergo strict quality control and testing to ensure that its various performance indicators comply with relevant national standards (such as GB/T 713), in order to ensure its safety

and reliability under design and usage conditions. Whether it's building large oil storage tanks, high-pressure vessels, or industrial boilers, Q345-R is a trusted choice for engineers.
