Shifts in measured hardness due to elevated temperature could lead to false acceptance or rejection of heat-treated parts.

L&L Special Furnace Co. Inc. shipped a floor-standing, high-temperature box furnace to a global supplier of piezo ceramics used in the military, aerospace and medical industries. The furnace, which has an effective work zone measuring 18 inches wide x 18 inches high x 36 inches deep, has a double-pivot horizontal door. It is used for processing glass products to 2500°F (1371°C). This process causes lead to outgas. As a result, the furnace interior is constructed of high-alumina refractory with less silica than normal linings, which helps delay the corrosive reaction between the silica present in the refractory and the lead outgassing at elevated temperatures.

Selecting a burner that meets emissions targets is imperative and requires a thorough understanding of the solutions available today.

PPG HI-TEMP 1027HD coating is a next-generation, ambient-cure coating engineered for challenging corrosion-under-insulation (CUI) conditions.

Designed for use by the steel, metals, industrial furnace and ceramic industries, versatile PSC-55N series pyrometers are ideal for precise temperature measurements from 392-5432°F (200-3000°C) and operate in the shortwave spectral range with fast, adjustable response time of 5 milliseconds to reduce or compensate for changes in target or surface emissivity.

When something so disruptive happens that hits daily life in unpredictable ways, adaptability becomes a key element, especially when it comes to business. We have seen many people adopting smart working, as face-to-face meetings and business trips have been replaced by frequent video calls.

The PBI facility, as part of their planned maintenance period, worked on one of the two reactors late last year. During the cleaning process, high-pressure water damaged one of the bushings on one of the reactors. Two of these specially made GRAPHALLOY® bushings are used in each reactor, which makes the polymer used to produce the fibers at the plant.

How much do you think you know about high-temperature corrosion, and what does “high temperature” really mean?

Unfortunately, the answer to this question is quite complex and is dependent on a host of variables, not all of which may be obvious.

This article discusses different types of direct-fired gas burners that can be used for high-temperature applications.
