Characterization and testing of refractories for glass tank melters

open access: yesCerâmica, 2001
Current and future research goals in our laboratories include the study of the attack of glass-contact refractories and of crown refractories in glass tank melters, under either air-gas or oxyfuel conditions.

Refractory Celiac Disease

open access: yesCurrent Opinion in Oncology, 2013
Concept of refractory coeliac disease (RCD) emerged in the past decade and refers to persistence of malnutrition and intestinal villous atrophy for more than 1 year strict gluten-free diet in coeliac patients. Diagnosis of this condition remains difficult and conditions treatment and follow-up.RCD has been subdivided into two subgroups according to the

An Investigation of the Effect of Pyrolytic Liquid Obtained From Waste Tire on the Corrosion Behaviours of MgO-C Refractories

open access: yesHittite Journal of Science and Engineering, 2019
In this study, corrosion behaviours of MgO-C refractories by incorporating different binders as phenolic resin and pyrolytic liquid obtained by waste tire pyrolysis were investigated. Moreover, the effect of porosity on the corrosion resistance of those

CORROSION OF BASIC REFRACTORIES IN COPPER METALLURGY

open access: yesActa Metallurgica Slovaca, 2015
Knowledge of corrosion processes on the melt – solid boundary is very important for life time of refractories and for refractory using design. The aim of this study was to realize and evaluate laboratory corrosion tests of three types basic refractories ...

Chronic migraine: treatability, refractoriness, pseudo-refractoriness [PDF]

open access: yesThe Journal of Headache and Pain, 2015
Chronic migraine (CM), a highly disabling condition affecting 2-3% of the general population, represents a difficult-to-treat disorder for its unclear pathophysiology, complex comorbidities, and disappointing response to available pharmacological treatments[1]. High quality evidence (≥2 RCTs) recommends the prophylactic use of onabotulinum toxin A (155-

Current research and latest developments on refractories used as ladle linings

open access: yes工程科学学报, 2019
Non-metallic inclusions significantly influence the properties of steels. Take heavy rail steel as an example, Al2O3 inclusions can become fatigue source under cyclic stress, resulting in the rupture of the steel.

Iron leaching from nonrefractory grade bauxite: Individual process optimization and prediction by using DOE

open access: yesInternational Journal of Ceramic Engineering & Science, 2022
Bauxite is an important raw material for the production of refractories. The availability of refractory grade ore worldwide is limited, and high iron contents in particular reduce the quality of the material.

Review on the elaboration and characterization of ceramics refractories based on magnesite and dolomite

open access: yesJournal of Asian Ceramic Societies, 2016
One of the most important elements of furnaces, boilers and other heating units is the structure (lining), usually made of silica–alumina, basic or special refractories.

Study of the addition of a chemical mix additive and curing temperature on the setting time and mechanical properties of no‐cement castable

open access: yesInternational Journal of Ceramic Engineering & Science, 2022
Tight installation schedules and economic pressures are potential drawbacks for castable installation and performance. Many factors influence the setting behavior and the properties of no‐cement castable refractories, including temperature and chemical ...
