At Keen, we strive to provide unique custom oven solutions for a variety of parts preheating applications. The Keen K-PHB is another example of a custom preheat oven suitable to fit through narrow hatches found on today's naval ships. There are a wide variety of welding applications that require preheating steel before welding, and this particular client needed to have tight control over the preheating of couplings before welding them to a steel substrate.
The logistical aspect of installing an oven at the location of welding on a ship can be problematic, so a custom oven is often requested to suit the specific part and the process. The welding engineers wanted to have the part preheated very close to the weld zone in order to prevent any temperature variance in the part after the oven is removed from the oven. The engineers were well aware of the importance in preheating and postheating (stress-relief) the part before welding, and that if the proper procedures were not followed that the coupling could cool too quickly resulting in stress fractures and cracking in the weld.
The K-PHB hatchable preheat oven needed to be hand-carried to the
weld location, so had to be light enough to carry. For this
particular preheating steel before welding application we designed a
custom industrial oven from scratch and called it the K-PHB. This
unit is outfitted with our unique dial-digital controller with extra
bright-temperature display. The oven can be mounted on a bench for
easy access, and is front-loading with flat interior shelves. The K-
PHB preheating oven is front-loading.
K-PHB Industrial Oven Specifications:
Shelving Style: Perforated Steel - One Lower Shelf / One Upper Shelf
This is an font-loading industrial oven that is positioned vertically, and can fit through hatches on ships. This digital dial thermostat is our standard digital unit with an ambient-550F temperature adjustment range. It's important to note that the door hinges on the K-PHB hatchable oven are tack welded to the oven frame and not screw mounted. This allows for a long product life. Always beware of any industrial ovens that do not have welded hinges. This oven is powder-coated - as with all our ovens - at our in-house paint facility and is highly durable for a wide variety of industrial settings. There are 2 locking draw pull catches to clamp the door closed when in use and to prevent the door from opening causing the parts to fall out. It is a rugged oven and can be used in a variety of applications.
The K-PHB custom oven is constructed of carbon steel and is insulated throughout. It has a 500W heating element installed at the bottom of the oven behind a perforated steel grate to prevent the ship couplings from coming in direct contact with the element, but at the same time to allow the heat to radiate into the oven chamber. There were shelves installed this oven as requested - one shelf is actually the perforated grate that covers the element.
All our preheating ovens are made in the USA and feature a 1-year
limited manufacturer's warranty. Parts are readily available. Click here to see samples of our Custom Batch Ovens.
Frequently Asked Questions:
Q. What is a preheat oven?
Q. Can this hatchable oven be modified for other applications?
Q. Do you provide CAD drawings for review?
A. Yes. Keen's custom oven design process typically begins with a discussion of the various solutions we are able to provide to the client. If the client wants to proceed, we then do a CAD drawing for review that clearly outlines the custom oven design for the client to review.
Q. Do you manufacture gas-fired ovens?
